How to Choose the Correct 12V 12.5A PC LCD/Monitor/TV Power Adapter?
The first thing to consider for the LCD Monitor Power Supply is the voltage. The easiest way to check this is to turn your original 12V 12.5a PC LCD/Monitor/TV Power Adapter over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V attached to it, such as 12V, 14V, 24V and so on. This information is also available on the original adapter, if it is available.

The second thing to look for is the adapter current output needed for the LCD Monitor Power Supply. This number will have an A of mA associated with it. For example, it may say something like 1.58A, 2.1A, 3.42A, 3.5A, 4.74A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

Once these two issues have been settled, the other important step is simply to make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the LCD Monitor Power Supply will not matter if it is not able to be connected. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.

Many may choose the safest route possible and go with a replacement laptop adapter directly from the manufacturer, if available. While this is a good option, these parts may be more expensive than others that may be available from after-market manufacturers. Further, as long as the numbers match, all should work nearly the same and be just as safe and effective.
